Ed, While it does not directly answer your question, we have a bunch of Flash Drives (SSD Drives) installed for about two years now that we use for performance testing.
We don't use them every day, but when we do use them we beat the begeezus out of them with both reads and writes. Our Open system brothers at HDS have being doing it for even longer than us, and usually hit them with IO beaters much harder than we do. To the best of my knowledge the Flash Drives have been more reliable than HDD, and there's been no sudden flurry of failures after two or three years of some spurious heavy duty write activity.
